This patch adds the vendor and device id for the Mobilcom Debitel UMTS surf
stick (a.k.a. 4G Systems XSStick W14, MobiData MBD-200HU, ...).
To see these ids, you need to switch the stick to modem operation first
with the help of usb_modeswitch. This makes it switch from 1c9e:f000 to
1c9e:9603 and thus be recognized by the option driver.

The use of urb->actual_length to update tx_outstanding_bytes
implicitly assumes that the number of bytes actually written is the
same as the number of bytes we tried to write. On error that
assumption is violated so just use transfer_buffer_length the number
of bytes we intended to write to the device.
If an error occurs we need to fall through and call
usb_serial_port_softint to wake up processes waiting in
tty_wait_until_sent.

Add D-Link DWM-162-U5 device id 1e0e:ce16 into option driver. The device
has 4 interfaces, of which 1 is handled by storage and the other 3 by
option driver.
The device appears first as CD-only 05c6:2100 device and must be
switched to 1e0e:ce16 mode either by using "eject CD" or usb_modeswitch.
The MessageContent for usb_modeswitch.conf is:
"55534243e0c26a85000000000000061b000000020000000000000000000000"

This patch presents fixes for the autosuspend feature implementation in
sierra usb serial driver in functions sierra_open(), sierra_close() and
stop_read_write_urbs().
The patch "sierra_close() must resume the device before it notifies it
of a closure" submitted by Oliver Neukum on Wed, October 14 has been
merged as fix in sierra_close() function.
The bug fix in sierra_open() function restores the autopm interface
state on error condition.
The bug fix in in stop_read_write_urbs() function assures that both
receive and interrupt urbs are recycled.

This patch presents a fix for the autosuspend feature implementation in
sierra usb serial driver for function sierra_send_setup(). Because it
is possible to call sierra_send_setup() before sierra_open() or after
sierra_close() we added a get/put interface activity to assure that the
usb control can happen even when the device is autosuspended.

many serial subdrivers are clearly written as if throttle/unthrottle
cannot sleep. This leads to unneeded atomic submissions. This
patch converts affected drivers in a way to makes very clear that
throttle/unthrottle can sleep. Thus future misdesigns can be avoided
and efficiency and reliability improved.
This removes any such assumption using GFP_KERNEL and spin_lock_irq()

The generic usbserial driver in Linux 2.6.31 halts its receiving
channel in response to throttle requests from the line discipline.
Unfortunately it drops the contents of the first URB received after
throttling takes effect. This patch corrects that problem.

This patch (as1293) fixes a problem with the ipaq serial driver. It
tries to bind to all the interfaces, even those that don't have enough
endpoints. The symptom is an invalid memory reference and oops when
the device is plugged in.

This patch (as1295) fixes a recently-added bug in the USB serial core.
If certain kinds of errors occur during probing, the core may call a
serial driver's release method without previously calling the attach
method. This causes some drivers (io_ti in particular) to perform an
invalid memory access.
The patch adds a new flag to keep track of whether or not attach has
been called.
